According to the company public relations manager Deborah Kangende, the tariffs have been upped by seven percent.
Kangende said the upward adjustment had been approved by the National Water and Sanitation Council (NWASCO) for the period 2019.
Kangende disclosed that the bills to be sent out in February, 2019 will be based on the new tariff adjustments.
She said other charges such as Kiosk charges, vacuum tanker hires among others will remain the same.
Kangende said the adjustment has been effected to cushion the company from the inflation of operational costs in order to meet standard operational service.
